Most industrial wastes are environmentally harmful. First of all, this applies to chemical wastes containing leachable organic and inorganic components. Leaky or poorly sealed landfills lead to groundwater seepage. They are typically characterized by high levels of ammonia, arsenic, chromium, lead, copper, zinc, iron, and organic compounds. The results of laboratory analyses of landfill leachates seeping into the soil and water environment are presented and quantitative changes in groundwater flowing from the area of the landfill under study are discussed.
